Being boxed in to a particular area of practice has “never really appealed” to Virginia Crawter. Instead, she has looked to pave her own way in law, allowing her — as a senior legal counsel — to operate in ways that make sense to her, thereby allowing her to provide as much benefit to a business as possible. On this episode of The Corporate Counsel Show, host Jerome Doraisamy is joined by Main Sequence head of legal and company secretary Virginia Crawter to discuss the lessons she's learnt from her varied legal career, whether moving in-house has better allowed her to tick the vocational boxes that are most important to her, the day-to-day of in-house government roles and well as what life looks like for in-house VC lawyers, as well as the headline challenges faced by such professionals. Ms Crawter also outlines what crafting her own adventure means to her, how and why she realised such a mindset would be so important for her journey, how to communicate with colleagues and executives about such an approach, the values or outcomes that one needs to understand, how to respond to resistance to crafting one's own adventure, pushing back on traditional structures and how other in-house lawyers can better shape their vocational direction in the post-pandemic market.

The dark side of galaxy stellar populations II: The dependence of star formation histories on halo mass and on the scatter of the main sequence by Laura Scholz-Diaz et al. on Wednesday 23 November Nearby galaxies are the end result of their cosmological evolution, which is predicted to be influenced by the growth of their host dark matter halos. This co-evolution potentially leaves signatures in present-day observed galaxy properties, which might be essential to further understand how the growth and properties of galaxies are connected to those of their host halos. In this work, we study the evolutionary histories of nearby galaxies both in terms of their host halos and the scatter of the star-forming main sequence by investigating their time-resolved stellar populations using absorption optical spectra drawn from the Sloan Digital Sky Survey. We find that galaxy star formation histories depend on the masses of their host halos, and hence they shape the evolution of the star-forming main sequence over cosmic time. Additionally, we also find that the scatter around the z=0 star-forming main sequence is not (entirely) stochastic, as galaxies with currently different star formation rates have experienced, on average, different star formation histories. Our findings suggest that dark matter halos might play a key role in modulating the evolution of star formation in galaxies, and thus of the main sequence, and further demonstrate that galaxies at different evolutionary stages contribute to the observed scatter of this relation. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.11779v1

The Molecular-Gas Main Sequence and Schmidt-Kennicutt relation are fundamental, the Star-Forming Main Sequence is a useful byproduct by William M. Baker et al. on Tuesday 22 November We investigate the relationship between the star formation rate (SFR), stellar mass ($M_*$) and molecular gas mass ($M_{H_2}$) for local star-forming galaxies. We further investigate these relationships for high-z (z=1-3) galaxies and for the hosts of a local sample of Active Galactic Nuclei (AGN). We explore which of these dependencies are intrinsic and which are an indirect by-product by employing partial correlation coefficients and random forest regression. We find that for local star-forming galaxies, high-z galaxies, and AGN host galaxies, the Schmidt-Kennicutt relation (SK, between $M_{H_2}$ and SFR), and the Molecular Gas Main Sequence (MGMS, between $M_{H_2}$ and $M_*$) are intrinsic primary relations, while the relationship between $M_*$ and SFR, i.e. the Star-Forming Main Sequence (SFMS), is an indirect by-product of the former two. Hence the Star-Forming Main Sequence is not a fundamental scaling relation for local or high-redshift galaxies. We find evidence for both the evolution of the MGMS and SK relation over cosmic time, where, at a given stellar mass, the higher the redshift, the greater the molecular gas mass and the star formation efficiency. We offer a parameterisation of both the MGMS and SK relation's evolution with redshift, showing how they combine to form the observed evolution of the SFMS. In addition, we find that the local AGN host galaxies follow an AGN-MGMS relation (as well as a AGN-SK relation), where the MGMS is offset to lower $M_{H_2}$ for a given $M_*$ compared to local SF galaxies. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.10449v1

Unstable Mass Transfer from a Main-Sequence Star to a Supermassive Black Hole and Quasi-Periodic Eruptions by Itai Linial et al. on Monday 21 November We discuss the formation and evolution of systems comprised of a low-mass ($M_star lesssim 4 , rm M_odot$) main sequence star, orbiting a $10^5-10^7 , rm M_odot$ supermassive black hole with an orbital period of order $sim$hours, and a mild eccentricity ($eapprox0.1-0.2$), episodically shedding mass at each pericenter passage. We argue that the resulting mass transfer is likely unstable, with Roche lobe overflow initially driven by gravitational wave emission, but then being accelerated by the star's expansion in response to its mass loss, undergoing a runaway process. We show that such systems are naturally produced by two-body gravitational encounters within the inner parsec of a galaxy, followed by gravitational wave circularization and inspiral from initially highly eccentric orbits. We argue that such systems can produce recurring flares similar to the recently identified class of X-ray transients known as Quasi-Periodic Eruptions, observed at the centers of a few distant galaxies. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.09851v1
Long-term Photometric Study of the Pre-main Sequence Star V1180 Cas by Asen Mutafov et al. on Tuesday 18 October In this paper results from the optical photometric observations of the pre-main-sequence star V1180 Cas are reported. The star is a young variable associated with the dark cloud Lynds 1340, located at a distance of 600 pc from the Sun in the star forming region in Cassiopeia. V1180 Cas shows a large amplitude variability interpreted as a combination of accretion-induced and extinction-driven effects. Our data from VRI CCD photometric observations of the star are collected from September 2011 to February 2022. During our monitoring, we recorded several brightness dips with large amplitudes of up to 5 mag. (I-band). At the same time, increases in brightness over periods of several weeks have also been recorded. In this paper, we compare the photometric data obtained for V1180 Cas with observations of other low-mass pre-main sequence objects. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.09660v1
Aging of galaxies along the morphological sequence, marked by bulge growth and disk quenching by Louis Quilley et al. on Tuesday 18 October We revisit the color bimodality of galaxies using the extensive EFIGI morphological classification of nearby galaxies. The galaxy SDSS images in the g, r and i bands are decomposed as bulge+disk using SourceXtractor++. The spectral energy distributions made of our gri photometry complemented with GALEX NUV are fitted with ZPEG in order to estimate the stellar masses and specific star formations rates (sSFR) of whole galaxies as well as their bulge and disk components. The absolute NUV-r color versus stellar mass diagram shows a continuous relationship between the present sSFR of galaxies and their stellar mass, that spans all morphological types of the Hubble sequence. Irregular galaxies to Sab spirals make up the Blue Cloud, the Green Plain (formerly Valley) is made up of early-type spirals (S0a-Sa) while the Red Sequence contains all lenticular and elliptical galaxies, with systematically higher masses for the ellipticals. Galaxies across the Green Plain undergo a marked growth by a factor 2 to 3 in their bulge-to-total mass ratio and a systematic profile change from pseudo to classical bulges, as well as a significant reddening interpreted as star formation fading in their disks. Therefore, the Green Plain is a transition region, and we exclude a predominantly quick transit due to rapid quenching. We suggest that tracers of increased star formation (bright HII regions, spiral arms, flocculence) determine the limited scatter of the Main Sequence of star-forming galaxies. The high frequency of bars for all spirals as well as the stronger spiral arms and flocculence in the knee of the Green Plain suggest that internal dynamics, likely triggered by flybys or mergers, may be the key to the bulge growth of massive disk galaxies, marker of the aging of galaxies from star forming to quiescence. The Hubble sequence can then be considered as an inverse sequence of galaxy physical evolution. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2206.04707v2
Tidal Disruption of Main-Sequence Stars by Intermediate-Mass Black Holes by Fulya Kıroğlu et al. on Monday 17 October We study close encounters of a $1,M_{odot}$ middle-age main-sequence star (modelled using MESA) with massive black holes through hydrodynamic simulations, and explore in particular the dependence of the outcomes on the black hole mass. We consider here black holes in the intermediate-mass range, $M_{rm BH}= 100-10^4,M_{odot}$. Possible outcomes vary from a small tidal perturbation for weak encounters all the way to partial or full disruption for stronger encounters. We find that stronger encounters lead to increased mass loss at the first pericenter passage, in many cases ejecting the partially disrupted star on an unbound orbit. For encounters that initially produce a bound system, with only partial stripping of the star, the fraction of mass stripped from the star increases with each subsequent pericenter passage and a stellar remnant of finite mass is ultimately ejected in all cases. We also find that the number of successive close passages before ejection decreases as we go from the stellar-mass black hole to the intermediate-mass black hole regime. For instance, after an initial encounter right at the classical tidal disruption limit, a $1,M_{odot}$ star undergoes 16 (5) pericenter passages before ejection from a $10,M_{odot}$ ($100,M_{odot}$) black hole. Observations of consecutive electromagnetic flares from these repeated close passages could in principle be used to determine the mass of the black hole, thus possibly proving the existence of intermediate-mass black holes. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08002v1
A model for the infrared-radio correlation of main-sequence galaxies at GHz frequencies and its dependence on redshift and stellar mass by J. Schober et al. on Monday 17 October The infrared-radio correlation (IRRC) of star-forming galaxies can be used to estimate their star formation rate (SFR) based on the radio continuum luminosity at MHz-GHz frequencies. For application in future deep radio surveys, it is crucial to know whether the IRRC persists at high redshift z. Delvecchio et al. (2021) observed that the 1.4 GHz IRRC correlation of star-forming galaxies is nearly z-invariant up to z~4, but depends strongly on the stellar mass M_star. This should be taken into account for SFR calibrations based on radio luminosity. To understand the physical cause of the M_star-dependence of the IRRC and its properties at higher z, we construct a phenomenological model for galactic radio emission involving magnetic fields generated by a small-scale dynamo, a steady-state cosmic ray population, as well as observed scaling relations that reduce the number of free parameters. The best agreement between the model and the characteristics of the IRRC observed by Delvecchio et al. (2021) is found when the efficiency of the SN-driven turbulence is 5% and when saturation of the small-scale dynamo occurs once 0.5% of the kinetic energy is converted into magnetic energy. Generally, we find that the observed mass dependence of the IRRC appears as long as synchrotron emission dominates the galactic radio flux. When extrapolating the reference model to higher redshift, the free-free emission and absorption strongly affect the radio spectrum, which ultimately leads to an inversion of the M_star dependence of the IRRC at z>5. This could be tested with future deep radio observations, which will also probe the dependence of IR/radio flux ratios on galaxy orientation that is predicted by our model for high-z systems. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.07919v1

(2021) observed that the 1.4 GHz IRRC correlation of star-forming galaxies is nearly z-invariant up to z~4, but depends strongly on the stellar mass M_star. This should be taken into account for SFR calibrations based on radio luminosity. To understand the physical cause of the M_star-dependence of the IRRC and its properties at higher z, we construct a phenomenological model for galactic radio emission involving magnetic fields generated by a small-scale dynamo, a steady-state cosmic ray population, as well as observed scaling relations that reduce the number of free parameters. The best agreement between the model and the characteristics of the IRRC observed by Delvecchio et al. (2021) is found when the efficiency of the SN-driven turbulence is 5% and when saturation of the small-scale dynamo occurs once 0.5% of the kinetic energy is converted into magnetic energy. Generally, we find that the observed mass dependence of the IRRC appears as long as synchrotron emission dominates the galactic radio flux. When extrapolating the reference model to higher redshift, the free-free emission and absorption strongly affect the radio spectrum, which ultimately leads to an inversion of the M_star dependence of the IRRC at z>5. This could be tested with future deep radio observations, which will also probe the dependence of IR/radio flux ratios on galaxy orientation that is predicted by our model for high-z systems. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.07919v1
A non-interacting Galactic black hole candidate in a binary system with a main-sequence star by Sukanya Chakrabarti et al. on Tuesday 11 October We describe the discovery of a solar neighborhood ($d=474$~pc) binary system consisting of a main-sequence sunlike star and a massive non-interacting black hole candidate. We selected this system from the textit{Gaia} DR3 binary catalog based on its high mass ratio and location close to the main sequence. The spectral energy distribution (SED) of the visible star is well described by a single stellar model, indicating that no contribution from another luminous source is needed to fit the observed photometry. We derive stellar parameters from a high S/N Magellan/MIKE spectrum, classifying the star as a main-sequence star with $T_{rm eff} = 5972~rm K$, $log{g} = 4.54$, and $M = 0.91$~msun. The spectrum also shows no indication of a second luminous component. We have measured radial velocities of this system with the Automated Planet Finder, Magellan, and Keck over the past three months, which we use to determine the spectroscopic orbit of the binary. We show that the velocity data are consistent with the textit{Gaia} astrometric orbit and provide independent evidence for a massive dark companion. From a combined fit of the astrometric and spectroscopic data, we derive a companion mass of $11.9^{+2.0}_{-1.6}$msun. We conclude that this binary system harbors a massive black hole on an eccentric $(e =0.45 pm 0.02)$, long-period ($185.4 pm 0.1$ d) orbit. The main-sequence star that orbits this black hole is moderately metal-poor ($mbox{[Fe/H]} = -0.30$), on a Galactic orbit similar to thin disk stars. Our conclusions are independent of cite{ElBadry2022Disc}, who recently reported the discovery of the same system, and find a marginally lower companion mass than we do here. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.05003v1
A super-linear "radio-AGN main sequence'' links mean radio-AGN power and galaxy stellar mass since z sim 3 by I. Delvecchio et al. on Monday 26 September Mapping the average AGN luminosity across galaxy populations and over time encapsulates important clues on the interplay between supermassive black hole (SMBH) and galaxy growth. This paper presents the demography, mean power and cosmic evolution of radio AGN across star-forming galaxies (SFGs) of different stellar masses (${M_{*}}$). We exploit deep VLA-COSMOS 3 GHz data to build the rest-frame 1.4 GHz AGN luminosity functions at 0.1$leq$$z$$leq$4.5 hosted in SFGs. Splitting the AGN luminosity function into different ${M_{*}}$ bins reveals that, at all redshifts, radio AGN are both more frequent and more luminous in higher ${M_*}$ than in lower ${M_*}$ galaxies. The cumulative kinetic luminosity density exerted by radio AGN in SFGs peaks at $z$$sim$2, and it is mostly driven by galaxies with 10.5$leq$$log$(${M_{*}}$/${M_{odot}}$)$
Revisiting the Schönberg-Chandrasekhar limit in post main sequence stellar evolution by Shaswata Chowdhury et al. on Sunday 18 September The Sch"{o}nberg-Chandrasekhar limit in post main sequence evolution for stars of masses in the range $1.4lesssim M/M_{odot}lesssim 6$ gives the maximum pressure that the stellar core can withstand, once the central hydrogen is exhausted. It is usually expressed as a quadratic function of $1/alpha$, with $alpha$ being the ratio of the mean molecular weight of the core to that of the envelope. Here, we revisit this limit in scenarios where the pressure balance equation in the stellar interior may be modified, and in the presence of small stellar pressure anisotropy, that might arise due to several physical phenomena. Using numerical analysis, we derive a three parameter dependent master formula for the limit, and discuss various physical consequences. As a byproduct, in a limiting case of our formula, we find that in the standard Newtonian framework, the Sch"{o}nberg-Chandrasekhar limit is best fitted by a polynomial that is linear, rather than quadratic, to lowest order in $1/alpha$. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.07389v1

Accretion and extinction variations in the low-mass pre-main sequence binary system WX Cha by Eleonora Fiorellino et al. on Monday 12 September Light curves of young star systems show photometric variability due to different kinematic, and physical processes. One of the main contributors to the photometric variability is the changing mass accretion rate, which regulates the interplay between the forming young star and the protoplanetary disk. We collected high-resolution spectroscopy in eight different epochs, as well as ground-based and space-borne multi-epoch optical and infrared photometry of WX Cha, an M0 binary system, with an almost edge-on disk (i = 87degrees) in the Chamaeleon I star-forming region. Spectroscopic observations cover 72 days, the ground-based optical monitoring covers 42 days while space-borne TESS photometry extends for 56 days. The multi-wavelength light curves exhibit quasi-periodic variability of 0.35 - 0.53 mag in the near-infrared, and of 1.3 mag in g band. We studied the variability of selected emission lines that trace the accretion, computed the accretion luminosity and the mass accretion rate using empirical relations and obtained values of the accretion luminosity between 1.6 and 3.2 Lsun and mass accretion rate between 3.31x10{-7} Msun/yr and 7.76x10^{-7} Msun/yr. Our results show that WX Cha is accreting at a rate larger than what is typical for T Tauri stars in the same star-forming region with the same stellar parameters. We theorize that this is due to the higher disk mass of WX Cha than what is usual for stars with similar stellar mass, and to the binary nature of the system. Daily changes in the accretion luminosity and in the extinction can explain the photometric variability. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.04304v1

A special episode of the Watt Pod where we get to hear from both sides of the fence - the startup and the investor. Join us as Alexander Post (Co-Founder & CTO @ MGA Thermal) and Martin Duursma (Partner @ Main Sequence Ventures) give us the inside track on how they are powering the energy transition and what brought them together. We get to hear what a deep-tech investor is looking for in climatetech disruptors and some of the other areas of focus, including space travel. We also learn what it takes to develop a deeptech startup (hint: lots of research). MGA Thermal is enabling the shift to renewable energy by providing a new way to store energy that's clean, economical and scalable. They have invented a brand new type of thermal storage material capable of storing a huge amount of heat in a safe and easy way to use. This is enabling intermittent renewable energy sources to provide base load electricity to the grid. Main Sequence Ventures is a venture capital firm working with inventors who are building something hard from their unique expertise in science. They aim to bridge the ‘valley of death' between research and commercialisation solving the world's greatest challenges by turning scientific breakthroughs into next century's giants. Main Sequence was formed in 2017 to manage the CSIRO's innovation fund and now has two funds at close to $600M under management with 42 companies in the portfolio. https://www.mgathermalstorage.com/ https://www.mseq.vc/ --- Send in a voice message: https://anchor.fm/watt-pod/message

Food & Drink Business editor Kim Berry talks to deep tech venture capital company Main Sequence director Phil Morle about synthetic biology, Australia's role and potential in the sector and projects already underway. We look specifically at precision fermentation, its ability to recreate animal fats and why that will be key in shifting consumers to a plant-based diet.As the global population grows, the reality of needing to produce more food using less space becomes increasingly urgent. Phil talks about how science has done so much to significantly improved yield for current food production processes, and that it is now time to invest in and develop innovative new approaches to food production.Phil acknowledges that plant-based foods are already going a long way to help meet increased demand, but it is synthetic biology and the fermentation of various yeast forms that are allowing producers to directly grow food products. We discuss that this is well established – for example, synthetic insulin production – but we are now witnessing fermentation projects that can produce proteins and fats for dairy and meat substitutes.We look at early-stage innovations that are demonstrating viability, including Nourish Ingredients and Eden Brew. Phil then focuses on the effort involved in quickly transitioning these to market, scaling up to the volumes required to allow prices to approach, if not exceed, parity with traditional animal products.Australia's scientists and their research are taking synthetic biology solutions to the world and we wrap with likely timelines to progress current capability demonstrators and early production projects to a level where global capital can fund the required expansion here in Australia.------------------------------The Food & Drink Business Podcast is produced by Southern Skies Media on behalf of Food & Drink Business, owned and published by Yaffa Media.The views of the people featured on this podcast do not necessarily represent the views of Food & Drink Business, Yaffa Media, or the guest's employer.

Welcome to Bits, your daily tech news bulletin, for Tuesday, May the 4th be with you, I'm Seamus Byrne.A new partnership between the CSIRO and venture capital group Main Sequence is launching a new space industry startup, Quasar Satellite Technologies. The technology aims to enabled ground stations to communicate with hundreds of satellites at a time, with the potential to sell 'ground stations as a service' for the growing satellite market. The Australian technology set to underpin the new company comes from the development of Phased Array Feed technology used to in the Square Kilometre Array Pathfinder project – which was developed by the CSIRO team that invented Wi-Fi.https://www.innovationaus.com/quasar-is-csiros-latest-venture-science-bet/After its recent decision to end talks for a sale to Microsoft for over $10B, Discord has announced today it has taken investment from Sony Entertainment and will make Discord available within the PlayStation Network by next year. Today, Discord includes basic integration with Xbox – you can see what someone is playing, but not communicate with them. The PlayStation integration will go beyond that and allow communication as well, including from PlayStation consoles to Discord users on PC or mobile. The companies did not disclose the investment amount.https://venturebeat.com/2021/05/03/playstation-invests-in-discord-and-plans-integrating-with-psn-in-2022/Facebook is using some concerning language to try to convince its iPhone users to let it keep tracking users across other apps and websites.

Getting innovation from lab to market is not an easy feat, and few countries do it well. Australia’s research output, for instance, punches way above its commercial applications (e.g. #10 in the SJR ranking and Nature Index). Are there ways to accelerate that transformation? Australia set up Main Sequence Ventures (@mseqvc) as a AU$240M (about US$170M) deep tech fund backed by the CSIRO and private investors, to target that opportunity notably in domains such as ag-tech, synthetic biology, quantum and space (the CSIRO is the Australia’s federal government agency responsible for scientific research). This podcast is hosted by Benjamin Joffe, Partner at SOSV, a global early stage fund focused on deep tech. SOSV runs multiple accelerator programs including HAX (intelligent hardware) and IndieBio (life sciences). To hear about new episodes, sign up to the newsletter or follow us on twitter at @LabToMarket. For other episodes on foreign deep tech ecosystems, check out India and Japan. OVERVIEW In this episode, Phil Morle (@philmorle), partner and long-time pioneer of the country’s startup scene (wikipedia), explains the commonalities he found between entrepreneurs and scientists, how the fund extended its investment domains and helps compress development timelines. He closes with thoughts on the tough year it has been with fires, drought and Covid, and how returns and impact now go hand in hand, from responding to new threats, feeding the planet, to delivering healthcare at scale. Before Main Sequence Ventures, Phil had three lives: He spent a decade as a theatre director, learning how to create things from scratch. Another decade with startups including as CTO of Kazaa — the then-dominant P2P file-sharing service, And another as the founder of Australia’s first Silicon Valley-style startup incubator, called Pollenizer, where he also advised numerous organizations including the CSIRO (Commonwealth Scientific and Industrial Research Organisation) on setting up their own incubators. He was then tapped by the CSIRO to set up a fund to support the translation of Australian research into commercial applications, including the output of CSIRO’s 3,500 scientists. Among the lessons learned: How he got scientists to grow an entrepreneurial mindset. How to look for early proof points for the whole company. How spending too long in the science exclusively sends weak signals into the market. How deal creation is more valuable than mere deal assessment and de-risking. How they designed a plant-based meat company, assembled a team, and got a product to market in 9 months only. How bridge-building between scientific domains, business expertise and geographies is crucial to startup success. How Covid-19 has lit a fire in the innovation ecosystem.

A brief description of the Hertzsprung Russell (HR) Diagram and its primary feature known as the main sequence.
MacGregor Campbell is a science writer, animator, and former math teacher based in Portland, Oregon. He also released The Ownership Society, a heady, plunderphonics-heavy album, in 2006 under the moniker Main Sequence. Shaun encountered this largely internet-based object as a teenager and had a track-by-track discussion of the LP with MacGregor last fall.This week, Shaun also re-visits last week's episode by sharing a listener's comment and passing along information about one DIY punk's accessibility work before they briefly talk about plunderphonics and their "discovery" of The Ownership Society (1:15).After the break, Shaun talks with MacGregor about calling the project Main Sequence (9:10), the process of finding samples (9:53), and what MacGregor's been doing since (13:03) before discussing the album's messages in today's political context (19:10). From there, the two embark on a track-by-track breakdown of The Ownership Society, touching upon metaphysics, economics, and value(s) along the way. It's perhaps the Dropouts' nerdiest episode so far.Throughout the conversation, Shaun includes exclusive demo tracks from the vault, including "Gramian" (21:02), "Invoice" (38:37), and "Thinking and Doing" (50:42).To get in touch with MacGregor, you may email macgregor.campbell@gmail.com or follow him on Twitter at @mainsequence.The interview audio featured in this episode originally aired on November 10th, 2019 during Shaun's radio program, Anarchist Brunch, on WSUM 91.7 FM.
In this lecture we discuss how a low mass star evolves off the main sequence when it runs out of hydrogen to fuse in its core. We follow its evolution from the Main Sequence to a Red Giant to a Supergiant to a Planetary Nebula to a White Dwarf.

One of the most fundamental correlations between the properties of galaxies in the local Universe is the so-called morphology-density relation (Dressler 1980). A plethora of studies utilizing multi-wavelength tracers of activity have shown that late type star forming galaxies favour low density regions in the local Universe (e.g. G´omez et al. 2003). In particular, the cores of massive galaxy clusters are galaxy graveyards full of massive spheroids that are dominated by old stellar populations. A variety of physical processes might be effective in suppressing star formation and affecting the morphology of cluster and group galaxies. Broadly speaking, these can be grouped in two big families: (i) interactions with other cluster members and/or with the cluster gravitational potential and (ii) interactions with the hot gas that permeates massive galaxy systems. Galaxy groups are the most common galaxy environment in our Universe, bridging the gap between the low density field and the crowded galaxy clusters. Indeed, as many as 50%-70% of galaxies reside in galaxy groups in the nearby Universe (Huchra & Geller 1982; Eke et al. 2004), while only a few percent are contained in the denser cluster cores. In addition, in the current bottom-up paradigm of structure formation, galaxy groups are the building blocks of more massive systems: they merge to form clusters. As structures grow, galaxies join more and more massive systems, spending most of their life in galaxy groups before entering the cluster environment. Thus, it is plausible to ask if group-related processes may drive the observed relations between galaxy properties and their environment. To shed light on this topic we have built the largest X-ray selected samples of galaxy groups with secure spectroscopic identification on the major blank field surveys. For this purpose, we combine deep X-ray Chandra and XMM data of the four major blank fields (All-wavelength Extended Groth Strip International Survey (AEGIS), the COSMOS field, the Extended Chandra Deep Field South (ECDFS), and the Chandra Deep Field North (CDFN) ). The group catalog in each field is created by associating any X-ray extended emission to a galaxy overdensity in the 3D space. This is feasible given the extremely rich spectroscopic coverage of these fields. Our identification method and the dynamical analysis used to identify the galaxy group members and to estimate the group velocity dispersion is extensively tested on the AEGIS field and with mock catalogs extracted from the Millennium Simulation (Springel et al. 2005). The effect of dynamical complexity, substructure, shape of X-ray emission, different radial and redshift cuts have been explored on the LX −sigma relation. We also discover a high redshift group at z~1.54 in the AEGIS field. This detection illustrates that mega-second Chandra exposures are required for detecting such objects in the volume of deep fields. We provide an accurate measure of the Star Formation Rate (SFR) of galaxies by using the deepest available Herschel PACS and Spitzer MIPS data available for the considered fields. We also provide a well-calibrated estimate of the SFR derived by using the SED fitting technique for undetected sources in mid- and far-infrared observations. Using this unique sample, we conduct a comprehensive analysis of the dependence of the total SFR , total stellar masses and halo occupation distribution (HOD) of massive galaxies (M*>10^10 M_sun) on the halo mass of the groups with rigorous consideration of uncertainties. We observe a clear evolution in the level of star formation (SF) activity in galaxy groups. Indeed, the total star formation activity in high redshift (0.5

Trainer David Lanigan gives his views on his first ever Investec Derby runner Main Sequence
Transcript: It’s difficult to evaluate the possibility of life existing in a star after the main sequence stage. For the most massive stars, the death of the star is violent as a supernova which would almost certainly obliterate life on any planet that held it at the time of the star’s death. The stellar remnants are dark, neutron stars or black holes, with little prospect that they could lead to life. Lower mass stars like the Sun go through a giant phase. This enhancement of the envelope and heating up will probably also obliterate life in the terrestrial planet zone, but then the star becomes a white dwarf, not totally dark but with a habitable zone very small and very close to the star. All very low mass stars end this way as well, as white dwarfs. The universe is filled with white dwarfs, and these cooling embers of stars could potentially harbor life, perhaps by tidal heating of planets in elliptical orbits. But we have no way of evaluating the prospect.
Transcript: For Sun-like stars in the main sequence that are either more or less massive than the Sun, the prospect of life on planets around those stars is a trade off between the size of the habitable zone, and the number of planets it might contain, and the lifetime of the star. The highest mass main sequence stars, O and B stars, respectively a million and a thousand times the luminosity of the Sun, have lifetimes that are about one million and fifty million years. Far too little, we think, for complex life to develop before the stars go supernova. A stars and F stars, forming one and two percent of all main sequence stars respectively with twenty and seven times the luminosity of the Sun, live for a billion years in the case of A stars and two billion years in the case of F stars. Even for F stars, two billion years would only correspond to the time that it took to get multicelled organisms on Earth; then the star would die. So it seems that lower mass stars are the best possibilities. K stars, fifteen percent of all main sequence stars and a third the luminosity of the Sun, have main sequence lifetimes of twenty billion years, and the ubiquitous M stars, seventy-five percent of all main sequence stars with only 0.3 percent of the luminosity of the Sun, have main sequence lifetimes of hundreds of billions of years. However, their habitable zones are incredibly small, so the possibility of a planet existing at the right distance from such low luminosity stars is also small.
Transcript: The properties of stars in a star cluster as measured in the HR diagram change with time, and this can be a chronometer for measuring the age of groups of stars. The main sequence for a young star cluster is fully populated all the way up to the most massive, most luminous, and hottest stars. Remember that the main sequence runs from high luminosity and high temperature and high mass down to low luminosity, low temperature, and low mass. After ten to the seven years stars more than a thousand times the luminosity of the Sun have left the main sequence. After ten to the eight years stars more than a hundred times the luminosity of the Sun have left the main sequence. After ten to the nine years stars more than five times the Sun’s luminosity have left the main sequence, and after ten to the ten or ten billion years a star like the Sun is leaving the main sequence. Stars much less massive than the Sun have not had long enough in the age of the universe to exhaust their hydrogen, and so the main sequence is always populated in any star cluster for very low mass stars. This evolving point at which the most massive most luminous and hottest star exist on the main sequence is called the main sequence turnoff point.
Transcript: Imagine a set of stars with different masses, all of which are just reaching the main sequence and beginning to consume hydrogen for the first time. This is called the zero age main sequence. In theory it would be a line across the HR diagram, but in practice the properties of such stars form a band because stars of different ages have different chemical compositions which gives them slightly different observed properties.
Transcript: After the freefall gravitational collapse phase, a pre-main sequence star emerges. The collapse is inside out which is to say that the material near the center of the cloud collapses first followed by material further out. After only a few thousand years gravitational contraction releases sufficient energy to raise the temperature of the cloud, still not yet a star, to a few thousand Kelvin, and thus it can emit light. Convection also helps transmit energy to the outer regions of the cloud. In the case of a star like the Sun this process took less than a thousand years to produce a cloud about twenty times the size of the present day Sun and with a luminosity a hundred times that of the present Sun’s luminosity.
Transcript: There’s a simple formula to give an approximation for the lifetime of a main sequence star. The lifetime is the mass divided by the luminosity of the star, both in solar units, times nine billion years. However the lifetime does not depend exclusively on mass. As shown by theorists Russell and Vogt in the 1920s the final state of a main sequence star depends both on its mass and its chemical composition. For example a one solar mass star of three quarter hydrogen one quarter helium by mass composition can only form one stable configuration. However it will be a slightly different configuration from a one solar mass star made of half helium and half hydrogen. They will have different positions on the HR diagram. The Russell-Vogt theorem allows astronomers to calculate stellar evolution more accurately because as a star evolves it is continually changing its chemical composition by the conversion of hydrogen into helium, and thus the stable configuration of the star is also evolving with time.
Transcript: Intuitively we might expect a more massive star to last longer than a less massive star because it has more hydrogen to consume in the fusion process, but intuition does not work for stars because of the very steep and sharp relationship between luminosity and mass. If we want to use the analogy of a fuel tank, a large mass star does indeed have a larger fuel tank than a low mass star. However the efficiency or the rate of using that fuel is much, much faster and so the more massive star lasts far less long than the low mass star. It’s as if the most massive stars in the universe were extremely fuel inefficient gas guzzling cars that burn through their fuel at an enormous rate and don’t get very far on their tank full of gas even though the tank is large whereas the lowest mass stars in the universe are extremely gas efficient or fuel efficient. They’re miserly with their fuel, and although their fuel tank is small it lasts far longer than the gas guzzlers. Thus if we have a population of stars of different masses that form at the same time the most massive stars will die first. The least massive stars will last substantially longer.
Transcript: The steep relationship between mass and luminosity for main sequence stars has an important consequence for the lifetime of the stars. Consider a star that’s a tenth the mass of the Sun. In round numbers the luminosity is ten to the minus four times the luminosity of the Sun. Thus the size of the fuel reservoir is ten times smaller, but the rate of evolution is ten thousand times smaller. This means the star will last about a thousand times longer than the Sun. Instead of a total main sequence life of ten to the ten years, we have a total main sequence life of ten to the thirteen or ten trillion years. Compare it to the other end of the main sequence. A star of a hundred times the mass of the Sun in round numbers has a luminosity a million times that of the Sun. Although the fuel reservoir is a hundred times larger than the Sun, the rate of burning the fuel is a million times larger which means the star lasts ten thousand times less long than the Sun. Instead of a main sequence lifetime of ten billion years, we have a main sequence lifetime of roughly a million years.
Transcript: Main sequence stars are classified according to the system of spectral types developed almost a hundred years ago. Going from the hottest to the coolest stars there are O type main sequence stars whose mass is about fifty times that of the Sun, radius about twenty times, a temperature of forty thousand degrees, and a luminosity a million times that of the Sun. B stars have masses twenty times that of the Sun and radii seven times that, photospheres are thirty thousand Kelvin and the luminosity is about twenty thousand times that of the Sun. A stars masses three times that of the Sun and radius three times, ten thousand degree atmospheres, and eighty times the Sun’s luminosity. F stars mass of 1.7 times the Sun’s mass and radius 1.4 times, seventy-five hundred degree Kelvin for the photosphere, and six times the luminosity of the Sun. G stars, similar to the Sun, 1.1 times the mass and the radius, six thousand degree atmospheres, and 1.3 times the Sun’s luminosity. K stars 0.8 times the mass of the Sun and the same factor for the radius, five thousand degree atmospheres, and 0.4 solar luminosities. And the coolest M stars about a half the mass of the Sun, 0.6 times the solar radius, a photosphere of thirty-five hundred Kelvin and luminosity of 0.03 times the Sun’s luminosity.
Transcript: Main sequence stars have several basic properties. All main sequence stars are converting hydrogen to helium by the fusion process, and that’s responsible for the energy release and the radiation that leaves the stars. Main sequence stars are all stable with their internal structure governed by the principle of hydrostatic equilibrium. The most massive main sequence stars are more luminous, physically larger, and have hotter photospheres than low mass main sequence stars. Main sequence stars come in the mass range from about a tenth the mass of the Sun to about a hundred times the mass of the Sun, but the most abundant main sequence stars have around the mass of the Sun or lower.
Transcript: Conceptually we can divide the evolution of stars into three rough stages: the early stages or pre-main sequence stages of evolution, the main sequence itself when hydrogen is converted into helium, and post pain sequence stages which vary depending on the mass of a star. To take the example of the Sun, the Sun has spent roughly thirty million years reaching the main sequence, will spend nine billion years in total on the main sequence, followed by about a billion years as a red giant, and then a large or essentially infinite amount of time as a cooling white dwarf. What this implies for censuses of stars outside the main sequence is that the visibility of a star depends roughly on the amount of time that it spends in each evolutionary stage. So if a star like the Sun spends less than one percent of its time reaching the main sequence and about ten percent of its time as a red giant, then if we surveyed a hundred stars like the Sun at different stages of their evolution we’d find only about one on its way to the main sequence, ninety percent we’d find on the main sequence, and about ten percent we’d find as red giants. This is not the whole truth however because the different evolutionary stages have different luminosities, and short-lived but luminous stages of stellar evolution are much more visible than long-lived or dim stages of stellar evolution. Thus the stellar catalogs are over represented in the short-lived luminous stages such as red giants and of course supernovae.
Transcript: As was first seen nearly a hundred years ago, when luminosities and effective temperatures are gathered for hundreds of stars near the Sun, the result is not a scatter plot. Most stars in the H-R diagram lie on a diagonal line or track that runs from hot, luminous, and blue stars in the upper left corner down to cool, faint, and red stars in the lower right corner. Stars with these properties are called main sequence stars. The main sequence runs across the H-R diagram, and it represents all stars that get their energy from the fusion of hydrogen into helium.
